the never ending story...
In this posting I wrote that my Ubuntu system sometimes just hangs at the boot up. It happened again yesterday morning. I could boot into recovery mode, but when booting the full system I got the error message
ata1.00: failed to set xfermodeand after several minutes you end up in a extremely low run-level (initramfs -something) shell where the only useful command is reboot.
That seems to be a hardware problem, it appears in some SATA systems with a couple of motherboards. I solved it with this workaround. However it seems, that this does not reliably fix the business, there are some more options to try, but the involve fiddling around with the hardware or the BIOS.
